On async reads, page data is allocated before sending. When the response is received but it has no data to fill (e.g. STATUS_END_OF_FILE), __calc_signature() will still include the pages in its computation, leading to an invalid signature check. This patch fixes this by not setting the async read smb_rqst page data (zeroed by default) if its got_bytes is 0. This can be reproduced/verified with xfstests generic/465.
